For comparison I did the same with the stainless steel Berthouds which didn't suffer the same fate and has withstood various bumps into brick walls with barely a scratch.

I do look at this as someone who has used bikes with fenders for 30 years in a commuting environment where it will be placed in close proximity with other bikes.
These feel great for general riding but I don't know if they will survive that long if somebody accidentally hooks their pedals behind them while removing their bike from the rack.
